HAROLD L. HIENSZEY, OF PHILADELPHIA, PENNSYLVANIA.

LOCOMOTIVE-SUPERHEATER.

Specification of Letters Patent. Application filed July 21, 1911. Serial No. 639,748.

Patented May 21, 1912.

To all whom it may concern:

Be it known that I, HAROLD L. HENSZEY, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented .certain new and useful Improvements in Locomotive-Superheaters, of'which the following is a specification.

My invention relates to improvements in locomotive superheaters and has for its leading object the provisionof an improved super-heater for the steam generated in the locomotive which will serve to super-heat the said steam. and will continue the super- 15 heating action until the steam has almost reachedthe engine cylinder, whereby said steam will enter the cylinder in its hottest and driest state, thus possessinga maximum amount of-energy.

A further object of my invention is the provision of a superheater receiving the steam from the steam dome of the locomotive and conducting said steam into the fire space of the boiler, whereby the heat in said fire space will come more directly against the steam than it does against the water from which the steam is originally generated, and in this manner the steam will be superheated by the same heat that it has originally generated, and I will thusbe able by the use of my improved superheater to furnish hotter steam and thus produce more energy from the combustionof the same amount of fuel than is possible without the use of my improved superheater.

Other objects and advantages of my improved superheater will be apparent from the following description taken in connection with the accompanying drawings and it will be understood that I may make any mo'difications in the specific structure shown and described within the scope of my claims j without departing from or exceeding the spirit of the invention.

Figure, 1 represents a side elevation of my improved boiler. Fig. 2 represents a longitudinal sectional view thereof. Fig. 3 represents a .cross sectional view of the boiler .on the line 3-3 of Fig. 1. Fig. 4 represents a similar sectional view on the line 4-4 of Fig. 1. Fig. 5 represents a longitudinal sectional view illustrating a modified construction of my invent-Ion. Fig. 6 represents a I cross sectional view on the line 6-6 of Fig. 5 5. Fig. ,7 represents a fragmentary longitudinal sectional view of another modified con'- struction of steam ring, parts being broken away and shown in section, and Fig. 8 represents a cross sectional view on the line 88 of Fig. 7.

In the drawings, in which similar characters of reference are employed to denote corresponding parts in the several views, the numeral 1 designates the main casing of the boiler having the steam dome 2 and the fire box portion 3, while mounted within the casing 1 are the heads 4 and 5 to which are secured the connecting fire tubes 6. a water space 7 being provided above the fire box and surrounding the same by the inner casmg 8 lnto which the flanges 9 and 10 of the Figs. 2, 3, and 4, I have shown secured within the fire box chamber the steam ring 15 into which the end 13 of the pipe 11 projects, said ring having secured thereto the inwardly extending cone shaped spark deflector screen 16 and having formed in its inner face the apertures or sockets 17 normally closed by the plugs 18, while formed in the opposite face of the ring are a second set of apertures in which are secured the steam conducting pipes 19 which pass along through the fire tubes 6, the .steam from the pipe 11 thus passing into the hollow space 20 of the steam ring 15 and outward from the ring through the steam tubes 19. Said tubes 19 project from the outer end of the" fire tube 6 into the smoke chamber 21 toward the outer portion of which is secured the second steam ring 22 having the steam space 23 which receives the steam from the tube 19, said ring being rovided with a.

discharge pipe 2-1 to disc arge the steam from the ring 22 into the cylinder of the en-- gine. The ring 22 is likewise provided with the apertures 25 closed by the plugs 26, the apertures 17 and 25 removal of the tubes 19 in case of leakage of the same without rendering it necessary to take the entire ring off the ends of the va'ious tubes in order to replace the faulty to e. a.

permitting of the ready- In the modified construction shown in Figs. 5 and 6, in place of employing the steam ring comprising a plurality of sections, certain of the sections 31 having the inwardly projecting outer flanges 32 and inner flanges 33, said flanges 32 and 33 being provided with enlarged socketed portions l the sockets receiving'the fastenings 35 securing the cap plate sections 36 in in position. The sections 31 and 36 areboth formed with the outwardly projecting flanges 37 having recesses 38 formed in their faces to receive packing 39 to insure a steam tight joint beneath the sections, certain. of the sections having ribs or tenons fitting into the grooves or sockets 41 in the ad- 1 jacent sections to further insure steam tight each end of the fire tubes.

joints between the sections.

Fr'om-. the foregoing description taken in connection with the drawings, the construction of my improved superheater will be readily understood, and it will be seen that the steam originally generated by the com: bustion in the fire chamber and the contact of the water with the fire tube extending therethrough will, upon the opening of the throttle,'pass from the steam dome into one of the steam rings and thence from said ring or member through the pipes 19 into the other steam ring or member, said pipes 19 passing through the fire tubes and spaces containing the products of combustion at It will thus be seen that the heated gases and products of combustion in the fire box chamber will impinge against and heat the ring or steam containing member within said chamber, the said products then passing through the fire tube andaround the steam conducting tubes 19 withinthe fire tube,-thus superheating the steam withinthe said tubes 19,

the gases then further heating the second steam ring or member which is disposed within the flue chamber, and in thismanner the steam on its way to the cylinder of the engine is superheated and delivered in its most heated condition to the cylinder, while I have utilized 'to the fullest possible extent combustion of the the other end depending into the fire box chamber, a throttle for controlling the flow of.steam..thnough.sa-id ipe, a steam ring locatedin the fire box 0 amber, and secured on the depending end of the pipe, a plurality of tubes having one end in communication with the steam containing portion of the ring and having their intermediate portions disposed within the fire tube, a second steam ring secured on the other end of thesteam tubes and located within the flue chamber, said pipes having their opposite.

ends in direct, communication with the interior of bot-h rings, and a steam outlet pipe for conveying the steamfrom'th'e last named ring.

2. asteam ring secured within the fire box chamber, a second steam ring secured within the flue chamber, pipes extending through the fire tubes of the locomotive and con-- necting the two steam rings, said plpes having their. opposite ends in direct communication with both rings, a connection be-' tween the steam dome of the locomotive and the steam ring of the fire boxchamber, and

an outlet pipe extending from the other steam ring. A
